Please consider:
This is a small collection of tests looking at very specific areas of the PS1 hardware. The usefulness of these tests were to see what emulators had happened to accurately implement these specific usecases. However, since version 2.0.0, ePSXe has been deliberately targeting these tests to boost its reputation (as evident by an ePSXe developer updating this page the moment ePSXe 2.0.0 released). It is doing so at the expense of accuracy, rather than for the sake of it, as using the plugins and settings that would get these results causes serious bugs in actual games.
